SHOW COLUMNS and SHOW KEYS commands fill IS_table_read_plan in a special way - they don't set or use lookup_field_vals member. Added a "trivial_show_command" flag that signals that lookup_field_vals has no valid data, made EXPLAIN code honor it.

When ORDER BY ... LIMIT check whether it should switch from index IDX1 to index IDX2, it should not ignore the fact that IDX2 may have a potential range or ref(const) access. Istead, it should calculate their costs: there is now a saved range optimizer cost and code to re-calculate what best_access_path() calculated for ref(const). /* in current cost model these two can be very different numbers unfortunately */

Let range optimizer remove parts of OR-clauses for which range analysis produced SEL_TREE(IMPOSSIBLE). There is no need to remove parts of AND-clauses: either they are inside of OR (and the whole AND-clause will be removed), or the AND-clause is at the top level, in which case the whole WHERE (or ON) is always FALSE and this is a degenerate case which receives special treatment. The removal process takes care not to produce 1-way ORs (in that case we substitute the OR for its remaining member).

Merged lp:maria/maria-10.0-galera up to revision 3880. Added a new functions to handler API to forcefully abort_transaction, producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These were added for future possiblity to add more storage engines that could use galera replication.

IS [NOT] NULL predicate is sargable within an outer join. Range analysis only uses predicates from ON expressions, which have regular semantics (without null-complemented rows, etc). There is no reason not use IS [NOT] NULL predicates.

Discover P_S tables automatically. Most of this patch is code clean-up: - removed tests and code responsible for P_S tables correctness verification - always return error from ha_perfschema::create() - install/upgrade scripts won't create P_S tables anymore

mysqldump: - Added --log-queries to allow one to disable logging for the dump sql/log_event.cc: - Removed setting of enable_slow_log as it's not required anymore. sql/sql_parse.cc: - Set enable_slow_log to value of thd->variables.sql_log_slow as this will speed up tests if slow log is disabled. - opt_log_slow_admin_statements can now only disable slow log, not enable it. sql/sql_explain.cc: - Minor cleanup Other things: - Added sql_log_slow to system variables. - Changed opt_slow_log to global_system_variables.sql_log_slow in all files - Updated tests to reflect changes
